From 1970 to 1984, 189 patients with penetrating injury and 20 with blunt injury were treated at Grady Memorial Hospital. One hundred eight-five patients with penetrating injury (Group 1) and 9 with blunt injury (Group 2) required emergency laparotomy. In the remaining 15 patients (Group 3), the diagnosis of diaphragmatic injury was delayed from 18 hours to 15 years (mean, 8 months) after injury. ⋯ The presence of such an injury should be excluded before the termination of the exploratory procedure. Also, diaphragmatic injury should be suspected in patients with roentgenographic abnormalities of the diaphragm or lower lung field following trauma. The presence of diaphragmatic injury in such patients should be excluded with appropriate diagnostic studies to protect the patient from its late complications.

A study of 6,690 transthoracic intracardiac monitoring (TIM) catheters in 5,666 pediatric patients undergoing cardiac surgical procedures during a 10-year period demonstrates the safety of this monitoring method. The utility of TIM catheters in patients undergoing a modified Fontan procedure, those undergoing repair of tetralogy of Fallot, and those with elevated or labile pulmonary resistance is stressed. Right atrial (RA) and left atrial (LA) catheters are particularly safe; they have a low incidence of bleeding complications (RA = 0%, LA = 0.13%) and retention complications (RA = 0.15%, LA = 0.63%). ⋯ PA catheters placed through the wall of the atrium have a lower complication rate-approximately equal to that for RA and LA catheters. The benefits of TIM catheters far outweight the associated risks if care is exercised in placing and removing them, and if complications are rapidly recognized and aggressively managed. The continued use of TIM catheters in pediatric cardiac surgical patients is therefore strongly recommended.
